Abstract
A symbology reader having a replaceable window element. The window element is user replaceable and incorporates varying features for varying applications. By removing and replacing a window element, the user may provide a clear, uncontaminated surface through which light may enter or exit the reader. In some embodiments, the window element includes focusing elements for defining a target plane for a detector assembly within the reader. In one such embodiment, the reader also includes additional focusing elements for focusing spotter beams to aid a user in aligning the reader to the defined target plane. The window element also incorporates polarizers and color selected filters for optimizing the reader for specific applications. In one embodiment, the reader includes a protective rubber boot to provide shock protection and to releasably retain the window element in attachment to the reader. In an alternative embodiment, the reader includes a releasable tab to hold the window element in position on the reader.
